The APW7502A is a 5V/1.37A, 2MHz buck converter with a 7-bit current DAC to provide a well regulated current source for VCSEL and IR_LED applications. Through I2C interface, the start-up slew rate of the current source can be 8-segment adjustable and the regulated level can be adjusted too from 100mA to 1.37A in 10mA resolution. When the buck converter output is overloaded or short circuited, the device limits the current at a safety level to prevent catastrophic failure. The over-temperature protection shuts down the device when junction temperature reaches 150oC and will automatically resume operating when junction temperature cools down by 20oC. The cathode of the flash LED is referenced to GND, which improves thermal performance. The device is available in WLCSP1.42x1.42-9 package.

5.5V, 7A Low RDSON Power Load Switch with Current Monitoring
Features
General Description
The APL3535 is a power-distribution switch with some protection functions that can deliver current up to 7A. The device incorporates a 12mΩ N-channel MOSFET power switch that is controlled by an enable logic pin and has a SS pin dedicated to soft start ramp-up rate control that can be used in application where the inrush current is concerned. The APL3535 integrates some protection features, including current limit protection, over temperature protection. The current limit protection can protect down-stream devices from catastrophic failure by limiting the output current at current-limit threshold during over-load or short-circuit events. The over temperature protection function shuts down the N-channel MOSFET power switch when the junction temperature rises beyond 155°C. Other features include an accurate current monitor function. The device is available in lead free QFN2x2-12A package.
Features
- N-CH MOSFET RDS(ON): 12mΩ(typ.)
- Smaller than 1uA Shutdown Current
- Ultra-Low Quiescent Current: Less than 50uA

General Description
The APW6016 is designed for server management processor power system, which integrates 5 buck converters and one 0.5A sink/source VTT LDO into one single package. The PWM converters and VTT LDO output voltage can support VCORE, memory, memory bus termination and 1.8V/2.5V/3.3V I/O. Each VR voltage are programmable with high resolution via I2C interface. Moreover, the power-on and power-off sequences as well as soft-start time of these VR are controlled and programmable via I2C interface, providing versatility for system designers. The APW6016 provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Modulation mode (PFM), the APW6016 provides very high efficiency over light to heavy loads with loading-modulated switching frequencies. On VTQFN-32 Package, the Forced PWM Mode works nearly at constant frequency for low-noise requirements. The APW6016 features sufficient protections against over-current, over-voltage, short circuit and over-temperature to prevent catastrophic failure. A Power-On-Reset function monitors the voltage on SVIN prevents wrong operation during power on. The output voltage of VTT automatically tracks the voltage of half VOUT2. The VTT output voltage is only requiring 10µF of ceramic output capacitance for stability and fast transient response.
